Billy Martin Real Signature vs. Clubhouse Signature

[filmmaker]

I just had my 1976 AL Champions New York Yankees Team-Signed Baseball certified by PSA/DNA but after inspecting it, I noticed PSA said that the Billy Martin Signature is a "Clubhouse" Version.

I did hours of research to find out, I believe PSA made an error.
Below are examples. The "REAL" Signed Cut is right off the PSA Collectible Facts page. It is very similar to mine.

The Billy Martin Signature on my ball has a very week "Billy" but I am looking for your thoughts as to if you agree with PSA or agree with me.

Thanks for your time and expertise.

The one on the other ball looks more clubhouse. I agree with u.

I agree that the ball in the OP has a clubhouse Martin. Here is a good example of his signature circa 1976.

There are enough differences for me to believe it is a clubhouse sig.
